• Radiological Environmental Monitoring Program (REMP)- 2010 0 This report gives the results of the Radiological Environmental Monitoring Program*(REMP) for the year 2010. The REMP is a requirement of the Fort Calhoun Station*t (FCS) operating license. It was initiated prior to plant operation in 1973.The main purpose of the REMP is to ensure public safety by monitoring plantdischarges and assessing the effect, if any, of plant operations, on the environment.

• i Samples are collected that would account for various exposure pathways such as*ingestion, inhalation, adsorption and direct exposure.

Samples collected on a regular basis include: air, surface water, ground water, milk, vegetation, fish, sediment, and food crops. Direct radiation is measured by thermoluminescent dosimeters (TLDs).*I These samples and TLDs are sent to an independent vendor laboratory for analysis.*The vendor uses analytical methods that are sensitive enough to detect a level of* activity far below that which would be considered harmful. Locations for sample collection are based on radiological and meteorological data from the Annual Effluent* Release Report and information obtained from the Environmental Land Use Survey.S*Most samples, particularly indicator samples, are collected in a circular area within a five-mile radius of plant containment. (However, control locations are usually outside of five miles.) This circle is divided into sixteen equal sectors, each assigned an*identification letter "A" through "R" (note: letters "I" and "0" are not used, as they may be mistaken for the numbers "1" and "0"). Sector "A" is centered on North or zero*degrees.

Sectors are also given directional labels such as "West-Southwest" ("WSW"). Sample locations are listed by number along with their respective

• distances and direction from plant containment, in the Offsite Dose Calculation

• Manual (ODCM).When assessing sample results, data from indicator locations (those most likely to be*effected by plant operations) are compared to those from control locations (those*least or not likely to be effected).

Results from an indicator location which were* significantly higher than those from a control location, could indicate a plant-* attributable effect, and could require additional investigation.

• The results of the sample analyses, as required by the FCS Offsite Dose Calculation

• Manual (ODCM), are presented in the attached statistical tables in accordance with* Table 1 of Regulatory Guide 4.8, "Environmental Technical Specifications for Nuclear Power Plants." Sample collection was conducted by plant chemistry/environmental staff. A contract vendor (Environmental Inc., Northbrook, Illinois) performed sample* analyses, preparation of monthly reports and the statistical evaluation of sample*! results. All vendor analysis techniques met the sensitivity requirements as stated in*the ODCM.* Results for 2010 were within expected ranges and compared closely with historical

• results. The following is a review of specific sample results.P 0~Page 2 of 14 0 S S 0 S S 0 S S S S 0 0 S 0 0 S 0 0 0 S 0 S 0 S 0 S 1)Ambient Gamma Radiation Ambient gamma radiation is measured by thermoluminescent dosimeters (TLDs) provided by the vendor laboratory.

These dosimeters contain calcium sulfate phosphors and are processed quarterly.

Thirty-two new thermoluminescent dosimeters were added to the program during the fourth quarter of 2010.All sample results are within the range of historical data and displayed less than 10% difference when compared to historical averages.

No discrepancy between released effluents and resultant radiation dose measured was observed.

No changes in plant operation/procedures are required based upon observed impacts to the environment to date.10-Year Trend Comparison of TLD Locations Location Avg. Dose (mr/week) 2010 Avg. Dose (mr/week)A 1.38 1.30 B 1.45 1.43 C 1.47 1.50 D 1.25 1.28 F 1.41 1.43 G 1.32 1.30 H 1.47 1.45 1.55 1.45 J 1.60 1.55 K 1.52 1.45 N* 1.39 1.35 0* 1.36 1.33 P* 1.41 1.35 S* 1.45 1.45 L (Control) 1.27 1.28* At least 5-Year comparison due to data availability

2) Milk/Pasture Milk samples are collected every two weeks from the beginning of May through September, and monthly the rest of the calendar year. Indicator samples are collected from a herd of milk goats at a family farm located approximately

0.7 miles

from the plant in Sector K (South-Southwest).

The control samples are collected from a commercial dairy cow herd located approximately

9.9 miles

from the plant in Sector J (South). These locations are unchanged from last year.Page 3 of 14 0* All milk sample results for Iodine-1 31, Cesium-1 34, Cesium-1 37 and other*gammas were at the LLD for both indicator and control locations.

No plant-related effects were observed.0 3) Fish Fish are collected on an annual basis. Control samples are collected at a*location approximately twenty miles upstream of the plant (river miles 665 -*I 667). Indicator samples are collected in the immediate vicinity of the power* plant (river miles 644 -646). Several species of fish, important to commercial and recreational interest, representing all levels of the aquatic food chain are collected at both locations.

• All sample results are within the range of historical data. Results from both*control and indicator locations were less than LLD for all gamma emitters, indicating no plant-related effects.0 4) Food Crop Based on the results of the biennial Land Use Survey, the nearest high*deposition pathway for food crops is the Alvin Pechnik Farm in Sector H*(0.94 miles, 1630). Accordingly, vegetable samples were collected at Alvin*Pechnik Farm for the purposes of the 2010 REMP.*Samples were comparable with historical results and within the range of*results reported from the control location garden at Mohr Dairy.0 All results were at the LLD for all non-naturally occurring radionuclides.

No plant-related effects were observed.0 5) Sediment*River sediment samples are collected twice a year at an upstream control*location and a downstream indicator location.S All results were at the LLD for all non-naturally occurring radionuclides.

No plant-related effects were observed.0 6) Air Monitoring

• Air sample results for 2010 were well within historical limits for all locations.

• Additionally, all indicator locations showed results very similar to the control*locations.

7) Surface Water Water samples are collected upstream of the plant (control location) as well as half-mile downstream, and at a municipal water treatment plant on the north edge of Omaha.Results for Cs-1 34, Cs-1 37, and other gammas were all less than LLD.Tritium results were also less than LLD. No plant-related effects were detected.8) Ground Water Quarterly residential well water samples are collected at the following locations:

Station No. 15, Smith Farm, Station No. 20, Mohr Dairy, Station No. 33, Bansen Farm and Station No. 40, Herber Acreage. All sample results to date have been at the LLD except gross beta due to naturally occurring radionuclides.

Gross beta results have ranged from a low of 2.2 pCi/liter to a high of 36 pCi/liter, with an average gross beta for the year of 11.4 pCi/liter.

Strontium-90 analysis is being conducted on wells as part of the station's groundwater protection program.Page 5 of 14 0 S 0 0 0 0 S 0 0 S 0 0 S 0 0 0 0 S 0 0 0 S S 0 0 0 0 S S 0 0 0 0 S Table 1.0 Sample Collection Program.Number of Number of Samples Collection Sample Collected Sample Class Frequency Locations This Period Background Radiation (TLDs) Quarterly 47 91 Air Particulates Weekly 6 312 Airborne Iodine Weekly 6 312 Milk Semimonthly 2 22 Surface Water Monthly 3 36 Ground Water Quarterly 4 16 Fish Annually 2 5 Sediment Semiannually 2 4 Food Crops Annually 3 6 TOTAL 804 Page 6 of 14 0 0 0 0 S 0 0 0 S 0 0 0 0 0 0 0 0 0 0 S 0 0 S 0 0 0 0 0 0 0 0 S 9 Table 2.0 Radiological Environmental Monitoring Program Summary Reporting Period January-December, 2010 Docket No. 50-295 Name of Facility Location of Facility Fort Calhoun Nuclear Power Station -Unit 1 Washington, Nebraska ( County, State )Background Gamma 91 0.5 1.4 (87/87) OTD-2C-(I) 1.6 (1/1) 1.3 (4/4) 0 Radiation (0.7-1.6) 3.32 mi. @ 500 (1.2-1.3)(TLD) OTD-2K-(I) 1.6 (1/1)(mR/week) 2.52 mi. @ 205 0 Airborne GB 312 0.005 0.028 (260/260)

Environmental Inc. participates in interlaboratory comparison (cross-check) programs as part of its quality control program. These programs are operated by such agencies as the Department of Energy, which supply blind-spike samples such as milk or water containing concentrations of radionuclides unknown to the testing laboratory.

This type of program provides an independent check of the analytical laboratory's procedures and processes, and provides indication of possible weaknesses.

In addition, Environmental Inc. has its own in-house QA program of blind-spike and duplicate analyses.Vendor in-house spike sampling was performed without a failure and in-house blank analyses were performed within acceptable ranges.One failure was observed from QA samples performed as part of the Environmental Resource Associates Inter-laboratory Comparison Cross-check Program. Soil sample STSO-1219 experienced low results for Uranium U-233/234 and U-238 analyses.

The sample was re-performed using total dissolution, and produced acceptable results. One in-house duplicate sample SL-4884 was not within the required tolerance.

The analysis was re-performed successfully.

No reason for the failure was listed.These results indicate the vendor's ability to self-identify and correct any deviations from acceptable or expected results. The test results had no impact on Fort Calhoun samples and were documented as such by the vendor.Page 14 of 14 0 S 0 S S S 0 0 S 0 S S S S S 0 S 0 S 0 0 S 0 0 0 S 0 Environmental, Inc.-0?gMidwest Laboratory 700 Landwehr Road -Northibrook, IL 60062-23 10 phone (847) 564-0700 -fax (847) 564-4517 APPENDIX A INTERLABORATORY COMPARISON PROGRAM RESULTS NOTE: Environmental Inc., Midwest Laboratory participates in intercomparison studies administered by Environmental Resources Associates, and serves as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada. Results are reported in Appendix A. TLD Intercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also reported.

Appendix A is updated four times a year; the complete Appendix is included in March, June, September and December monthly progress reports only.January, 2010 through December, 2010 0 S 0 0 Appendix A Interlaboratory Comparison Program Results 0Environmental, Inc., Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. These programs are operated by agencies which supply environmental type samples containing concentrations of radionuclides known to the issuing agency but not to participant laboratories.

The purpose of such a program is to provide an independent check on a laboratory's analytical procedures and to alert it of any possible problems.Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant labbratories and specifies control limits. Results consistently higher or lower than the known values or outside the control 0limits indicate a need to check the instruments or procedures used.Results in Table A-1 were obtained through participation in the environmental sample crosscheck program Sadministered by Environmental Resources Associates, serving as a replacement for studies conducted*previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada.Table A-2 lists results for thermoluminescent dosimeters (TLDs), via International Intercomparison of Environmental Dosimeters, when available, and internal laboratory testing.0Table A-3 lists results of the analyses on in-house "spiked" samples for the past twelve months. All samples are prepared using NIST traceable sources. Data for previous years available upon request.0Table A-4 lists results of the analyses on in-house "blank" samples for the past twelve months. Data for previous years available upon request.*Table A-5 lists REMP specific analytical results from the in-house "duplicate" program for the past twelve months.

All activities, except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period.2.0. Single Measurements Each single measurement is reported as follows: x +/- s where: x = value of the measurement; s = 2s counting uncertainty (corresponding to the 95% confidence level).In cases where the activity is less than the lower limit of detection L, it is reported as: <L, where L = the lower limit of detection based on 4.66s uncertainty for a background sample.3.0. Duplicate analyses 3.1 Individual results: For two analysis results; xi +/- sl and x2 +/- s2 Reported result: x + s; where x = (1/2) (X- + x2) and s = (1/2) s2 +s2 3.2. Individual results: <L1 , <L2 Reported result: <L, where L = lower of Li and L2 3.3. Individual results: x +/- s, <L Reported result: x +/- s if x > L; <L otherwise.

4.0. Computation

of Averages and Standard Deviations

4.1 Averages

and standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations.

The average x and standard deviation s of a set of n numbers x 1 , x 2 ... xn are defined as follows:-1 _ x-_x_2 X = n x S= n-4.2 Values below the highest lower limit of detection are not included in the average.4.3 If all values in the averaging group are less than the highest LLD, the highest LLD is reported.4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma error is reported.4.5 In rounding off, the following rules are followed: 4.5.1. If the figure following those to be retained is less than 5, the figure is dropped, and the retained figures are kept unchanged.

As an example, 11.443 is rounded off to 11.44.4.5.2. If the figure following those to be retained is equal to or greater than 5, the figure is dropped and the last retained figure is raised by 1. As an example, 11.445 is rounded off to 11.45.4.6 Composite samples which overlap the next month or year are reported for the month or year in which most of the sample is collected.
